IMPROVEMENT IN NEEDLE-SETTERS AND THREADERS..

The Schedule referred to in these Letters Patent and making part of the same.

I,-CHARLES F. Man'rmn, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Sewing- Machine Needle- Setters and Threaders, of which the following is aspecification.

Figure l is a side elevation of my invention;

Figure 2 is'an edge view;

Figures 3 and 4 are views of parts in detail; and

Figure 5, a section through line :c-sv fig. 1.

The object of this invention is to provide means for accurately adjusting a sewing-machine needle in the needle-arm, and for threading said needle and It consists mainly of an extensible gauge for adjusting, and a peculiar arrangement of books for threading the needle, as will hereinafter more fully appear.

in the drawing- A represents a metallic plate bifurcated at both ends.

At one end of the plate A is pivoted the smaller plate B, which is provided with spring clamps G O.

D represents a gauge-plate, pivoted to plate A at the same point as plate B.

The edge of plate D, when in the position shown in fig. 1, forms a linewith the end of plate A, both of which are suitably marked in regular spaces.

Either of the plates B I) may be closed into the plate A, bctweenthe bifurcations thereof, like the blade of a pocket-knife.

The opposite end of. plate A is provided with bifurcations or flanges E, and an enlargement or recess, e opening from its lower side, shown in fig. 3.

F represents a needle attached to the W-shaped spring H, and projecting on each side thereof, the ends of which needle are providcd' with hooks,'which may be of different sizes, as shown in fig. 3.

The spring H, with needleeF, are inserted intothe recess e of plate A, one end of said needle being conceaiedwithin'said recess, and'the opposite end projecting slightly above and between flanges E, as shown in figs. 1 and 2. v

The spring H bears against the sides ofplate A and holds the needle F firmly in position, at the same time allowing it to be readily removed for reversing its position.

Operation. The needle is held in the clamps O and adjusted so that its eye shall projcct'as far from the upper edge of clamp G as it is desired to have it project from the bottom of the needle arm when in position, the distance being indicated by the divisions on the plates A D. WVhen the needle is thus adjusted the shank of the same is inserted in the socket oi the needlearm and confined by a set-screw in the usual manner, after which the clamps G C are removed.

The advantage of the'pivotcd gauge-plate D is, that, in machines where there is not suflicieut space between the needle-arm and the plate oi'the machine, (as in the lVeed and others,) the plate Dmay be closed into the plate A, as above described, and thus be out of the way; whilein machines wherein the needle-arm ishighcr, (as in the Wheeler& W'ilsom) the whole device may be employed,

The threading device is operated by inserting the.

hooked needle through the eye of the machine-needle and engaging said hook with the thread, and drawing the same through said eye, the flanges E guiding the hooks in the operation.

The reversible hooked needle F adapts the threading device to fine or coarse-eyedneedlcs, as hooks of any desired size can be used on either end oi the same; and in case of the breakage of one or both of the books, the whole can be removed and reversed or replaced without detriment to the plate A. If desired, needle F-may project from only one side of spring Having thus fully described my invention,

That 1 claim as new, and desire to secure by Letters Patent, is-

l. The, plate A, in combination with the pivoted gaugc-plate D and plate B, having clamps C 0', substantially as described.

2. The needle F, provided with one or two hooks, and attached 'to spring H, in combination with plate A, substantially as described. v

The combination in one instrument of the reversible and adjustable needle F with its springH, the pivoted plate B with its clamps O, and the pivoted gauge-plate D, all arranged and operating substantially as described.

In testimony whereof I have signed my name to this specification in messes.
